James Darren Siddons (commonly known as "Jamie"; born 25 April 1964) is an Australian cricketer, renowned for his involvement in Sheffield Shieldfirst-class cricket over a 16-year career. He initially played for Victoria, and later for South Australia.
On 23 November 1997 he broke David Hookes' Shield run record of 9,364, going on to make 10,643 runs in 146 games. He is considered by some to be one of the finest batsmen in Shield competition not to receive a regular international spot, having been given just one opportunity to represent Australia in a One Day International (ODI), in 1988, scoring 32.
